' 3 Claims. This invention relates to coin-controlled mech-- anism for releasing the locking mechanism of a dispensing apparatus, to permit the dispensing operation to be performed. v

The primary object of the invention is to provide a simplified form of coin controlled releasing means which will be composed of a minimum number of parts and may therefore be produced at small expense, and which will also be durable and unlikely to get out of order after a long period of use.

' This and other objects of the invention are accomplished by means of the construction hereinafter disclosed by the following specification and as illustrated inthe accompanying drawing in which:

Fig. 1 is a view in front elevation of the lower portion of a dispensing machine provided with an embodiment of my invention.

Fig. 2 is a view thereof in elevation of a portion of theright hand end of the machine.

Fig. 3 is a. similar view of the left hand end thereof.

Figs. 4, 5 and 6 are detail views of the coin controlled locking and releasing mechanism which is employed, showing the parts in diflerent positions.

Fig. '7 is a detail view in perspective of the operating arm.

The machine illustrated is of the common type,

in which a series of vertical package containing compartments III are provided, atthe bottom of each of which is a reciprocating ejector I2, which is operated by a handle [4, the dispensing operation being performed by merely pulling out the handle and permitting it to return to initial position by the action of a spring and a package being removed from the bottom of the stack of packagesgin the compartment on the return movement and delivered to a tray Hi. A crank shaft I8 is pivoted at its ends in the sides of the casing and extends beneath the ejectors in position to be engaged by a hook l9, which depends from each ejector, so that, when any one of the ejectors is pulled outward, the crank shaft is oscillated.

According to my invention, an angular shaped arm 20, shown in detail in Fig. 7 is secured to the right hand end of the shaft l8, so that when the shaft is moved rotatably in its bearings, on any one of the electors being pulled out,.the arm will "be swung therewith. A locking dog 22 is mounted on a pivot 24 and is provided with a hook 25 arranged to engage a shoulder 26 on arm 20, so that, unless the dog 22 is lifted from its position shown in Fig. 2, after a slight movement of ,2! by the dispensing mechanism, the arm arm 20 moves beyond the position in which it can will be locked against further movement, as shown in Fig. 4.

A releasing lever 23, is mounted on a pivot 30 fixed in the middle portion of the dog 22, said lever having a pin 32 projecting from one end, 5 which, in the initial position of the parts, is held in engagement with the end portion 34 of arm 20, and having a rigid finger-36, which extends from the opposite end thereof at right angles, see Fig. l.

A coin supportiia is formed integrally with the 0 arm 20 and projects right angularly therefrom directly beneath the finger 36. A coin passage 40 cpensat its lower end to the support 38, and studs 42, B3 are fixed in the casing at each side of said passage directly above said support, so that, when 15 a coin is delivered to said passage it becomes lodged on said support and is held in position therein by said pins, as indicated in Fig. 2.

With the above described arrangement, if no coin has been delivered to support 33, when the arm 20 is swung upward by the action of the crank arm I8 thereon, it will merely swing the lever 28 on its pivot 30 and the arm will immediately be locked by the dog 22 against further movement, as shown in Fig. 4.

If, however, a coin has come to rest on support 38, as shown in Fig. 2, the finger 36, on said lever will immediately be swung into engagement with the edge of the coin, so that further swinging movement of finger 36 is prevented, and on 30 further movement of arm 20, its end portion 34 will be forced upward against pin 32, causing the lever 23 to swing on its finger 36 as a fulcrum.

As a result the pivot'30 of lever 28 will be forced upward, causing the dog 22 to be swung upward on its pivot 24 to the position of Fig. 5, so that it is lifted out of position to engage the shoulder 26, thereby permitting complete operation of the dispensing mechanism, as shown in Fig. 6. As the 40 be locked by the dog 22, the coin support 38 carried by said arm will be moved from beneath the coin, which will then be free to fall into the money box, (not shown), as indicated in Fig. 6.

At times attempts are made to operate the dispensing mechanism so rapidly, by pulling out and pushing back an operating handle so quickly that the coin does not have timeto fall from the coin support, before the support is moved back beneath the coin, so that the dispensing mechanism could then be operated a second time without inserting an additional coin.

To prevent the machine from thus being defraudedthe attachment shown in Fig. 3 is provided. An arm 44 is secured on the left hand end 55 is once started it must be rested, so that it will with ratchet teeth 45, which are engaged by a pawl 48, so that when the dispensing operation completed. A rigid pin 41 is fixed in arm It and the return spring it, is conveniently attached thereto. A dog 49 is loosely mounted on a pivot 50 and has a longitudinally extending slot ii therein, comprising two portions disposed horizontally at different elevations and having an intermediate shoulder 52 at the front end of the lower slot portion. The pin 41 extends through said slot, so that the dos ll is supported in a nearly horizontal position thereby. In the normal, or the parts, the pin 41 is located in the rear end of the slot II, as shown in full lines in Fig. 3. If the dispensing mechanism is operated at normal speed, the pin 41 is moved forward in slot 5i and when the pin nearly reaches the point where it would engage the shoulder 52, the dog swings down so that the pin passes into the uppermost or front portion of the slot, the dog ll thus in no way affecting theoperation.

If, however, it is attempted to pull out a handle it too rapidly, the pin 41 will engage the-shoulder 82 before the dog has time to swing down, as indicated by the dotted line position of Fig. 3, and as a result the dispensing movement will be arbe necessary for the operator to push inward on the handle to a slight extent, before the operation can be completed.

As soon as this is done the dog 48 will swing 'down, so that the shoulder 52 will be disengaged from the pin 41, thereby permitting it to pass into the front portion of the slot, so that the dispensing operation may be completed.

The arrangement is such that the coin support I! will be moved from beneath the coin at the instant the pin 41 engages the shoulder II, so that it will fall into the money box, and consequently, it will be necessary to insert another coin before the dispensing operation can again be performed.

It is to be noted that, while the device 40, which regulates the speed at which the machine may be operated to perform the dispensing operation, may be advantageously employed in connection with the type of machine herein shown and described, in which the dispensing mechanism is normally locked and cannot be unlocked without inserting a coin, it may also be advantageously employed-in connection with a machine of the type shown in my Patent No. 2,040,983, dated May 19th, 1936, in which the dispensing mechanism is normally unlocked, but becomes looked after a short initial movement, if a coin has not been inserted, as the speed regulating device then permits the locking mechanism to function.
